摘要： A measuring device and method for horizontal dynamic impedance of specified foundation depth based on differential response analysis of pulse excitation. The measuring method is realized based on the measuring device. Two rigid piles with different lengths are embedded into different foundation depths. Motion characteristics of the two rigid piles in the process of collision impact with the outside are different under the same pulse excitation. Dynamic impedance of specified foundation depth is deduced from the formula according to the differential response. Single-degree-of-freedom oscillators are arranged on the pile heads of the two piles, and strain gauges are arranged on the bottoms of the single-degree-of-freedom oscillators to obtain stress states of the single-degree-of-freedom oscillators, thereby calculating the relative displacements of the single-degree-of-freedom oscillators. This is simple in structure, reliable in measurement and convenient in data collection and processing.

摘要： The disclosure provides a bridge foundation scouring monitoring sensor and a monitoring data analysis method thereof, and belongs to the technical field of bridge engineering. The disclosure solves the problem that an existing bridge foundation scouring monitoring technology cannot realize reliable, efficient and high-precision bridge foundation scouring depth monitoring. The bridge foundation scouring monitoring sensor comprises a cover plate, a lower fixing unit and scouring depth monitoring standard units fixedly disposed between the cover plate and the lower fixing unit. Each scouring depth monitoring standard unit comprises a supporting frame and an optical fiber vibration string disposed in the supporting frame; the upper end and the lower end of each optical fiber vibration string are both fixedly connected with the corresponding supporting frame; a plurality of polyhedral mass blocks are evenly distributed on each optical fiber vibration string from top to bottom; and a fiber Bragg grating is disposed at the upper portion of each optical fiber vibration string. The bridge foundation scouring monitoring sensor of the disclosure realizes long-term real-time monitoring on the scouring depth of a bridge foundation and has higher monitoring efficiency and reliability compared with the current monitoring technology.

摘要： A method and system determines in real time the bearing capacity of a foundation tamped by a high-speed hydraulic tamper. Four wireless acceleration sensors are arranged uniformly along tamping plate edges, sensor position tamping points are determined; the soil is tamped, the plate peak acceleration slows, tends to, and reaches stabilization in a range, a relationship curve between the tamping number and plate peak acceleration is determined; different loads are applied to the foundation to obtain corresponding settlements, coordinate axes are established, points are drawn according to each test data group and sequentially connected with a smooth curve to obtain a settlement-load curve, and the curve is fitted; a tamping number and foundation bearing capacity relationship is obtained; the two relationship curves are combined to obtain a relationship curve, and the foundation bearing capacity magnitude at a certain moment during the tamping operation is determined by using the acceleration index.

摘要： A cavity-type load box includes an oil cavity unit. The oil cavity unit includes a sealing plate with a U-shaped section and two flat plates with edges wrapped in the sealing plate and is provided with an oil injection structure. Liquid oil injected from the oil injection structure flows into the oil cavity unit. The edges of the two flat plates are wrapped in the sealing plate with the U-shaped section, so that after the liquid oil enters an oil cavity via the oil injection structure, the sealing plate is stretched under the pressure of the liquid oil to cause deformation of the oil cavity. As a stress required for deformation of the sealing plate is very small, the pressure generated by the liquid oil directly acts on an object on the upper or lower surface of the cavity-type load box, and accordingly, the object s pushed.
